I have a standalone harness and racetronix fuel pump kit. The harness has a fuel pump relay and so does the racetronix I believe. My question is, will wiring the standalone harness into the c100 gray wired add another fuel pump relay and does this affect anything like pump performance etc. thanks for any help

 

I would run both. The racetronix relay mounts in the back, near the tank. The only wire that runs to the front of the car is the power wire which goes direct to battery or alternator.

Use the stand alone's relay to trigger the racetronix relay. The racetronix's really is a big 40 amp if I remember, and has nice thick wire. It will carry the power great.

I run a factory (LS1) fuse and relay to trigger mine and it works great. For the first time since doing an LS1 swap on my car I feel like my fuel pump wiring is 100% solid and reliable.

Ok, that sounds good, thanks for the help. Hopefully I'll get the car finished this weekend.

 

You and I have similar goals my friend
